How to store historical records in a history table in SQL Server

Question

I have 2 tables, Table-A and Table-A-History.

• Table-A contains current data rows.
• Table-A-History c

Answer 1

Even though it consumes more space, having the history table containing the most recent record as well will save you pain on writing reports and seeing how changes occurred and when. Something worth thinking about in my opinion.

As far as performance, I would expect them to be identical. But, you certainly wouldn't want to delete the record (option 1's "move") from the non-hist table because you are using referential integrity between the two tables, right?
